Lesson 4 - Interactive and script mode

2. LEARNING OBJECTIVES
Learn how to write code in Python script
mode.

3. LEARNING OUTCOMES
I can save code in Python’s script mode...
I can get keyboard input from users...

4. [ slide 3 ]
STARTER
Up until now we have not saved any files. We have
worked in interactive mode.
We can also save and run files too – in script mode.
To open a new script mode window:
1. Open IDLE and then from the File menu choose New
Window
2. To save this file choose Save from the File menu.
Lesson outcomes:
 I can save code in Python’s script
mode...
 I can get keyboard input from
users...

5. [ slide 6 ]
#COMMENTING
#Comments are used in Python to indicate what some part of the
code does.
#Comments always appear in red.
Lesson outcomes:
 I can save code in Python’s script
mode...
 I can get keyboard input from
users...

6. [ slide 1 ]
MAIN TASK 1
1. Log in to your computer
2. Open Python IDLE
3. Copy the code below to get the program to count to 10
>>> number=1
>>> while number < 11:
print(number)
number = number+1
4. Now in interactive mode, re-write the code so it prints the first 10 square
numbers e.g. 1, 4, 9, 16, 25, 36 ...
Don’t forget to add #Comments to indicate what the code does.
Lesson outcomes:
 I can save code in Python’s script
mode...
 I can get keyboard input from
users...

7. MINI PLENARY
Feedback your solution to the
rest of the class.
Lesson outcomes:
 I can save code in Python’s script
mode...
 I can get keyboard input from
users...

8. [ slide 9 ]
MAIN TASK 2
Write a Python file called friendly_computer.py
When run it should:
 ask the user for their name and store it in a variable
 say Hello to the user using the user’s name
 tell the user that it was nice talking to them
 say “Bye [name]”
Hint: You have done most of this in interactive mode.
Do not forget to save your file and send it to your teacher.
Lesson outcomes:
 I can save code in Python’s script
mode...
 I can get keyboard input from
users...

9. PLENARY
Why add a comment to the beginning of your
code?
In which two modes can you write code in
Python?
Don’t forget to upload your work to Moodle.
